The unit converter goes beyond simple volume conversion: it accounts for ingredient density, so converting a cup of flour to grams gives you the real weight (125 g), not a generic liquid approximation. The calorie and macro calculator uses the clinically validated Mifflin-St Jeor equation to personalise your daily energy target and breaks it down into protein, carbohydrates, and fat based on your goal.
The cooking time calculator covers 11 cuts of meat and fish, adjusting for weight, cooking method, and doneness — and always shows safe internal temperature targets alongside time estimates. The baking substitutions guide covers more than 50 tested swaps for eggs, dairy, flour, sugar, and leavening agents, with vegan and gluten-free options flagged throughout.
